Pace and Cap - Sartin Methodology & The Match Up - View Single Post

To recap, the VDC rank (from Val4 and RDSS1) is the better rank of BL/BL or the actual VDC factor - that's where ties come from, and Doc Sartin's idea was to consider 2 such equally ranked horse as EQUAL and to separate (if needed) based on bet-time odds. V/DC is derived from a fairly complex calculation (paceline dependant) which measures deceleration relative to velocity during several segments of the race - see FU 70 - 72?? for Doc's white paper on VDC and some early readouts.

Richard, now that we can see the % diff of the actual VDC factor (on the Segments and Primary screens) and see the actual rank of that factor (and not just the merging of VDC+BL/BL, which we have traditionally seen), what I hear you saying is you think the actual VDC factor is stronger than the merged factor, so much so that (when you need to) you just go with the better actual VDC factor to separate tied VDC ranks. Did I understand you correctly?

And Ken, I hear you saying you focus on combo of best VDC rank and PoH Total Energy. Correct?

Again, someone put up a screenshot with some ties to discuss, and I am happy to clarify anything.

The research on the utility of the underlying factor (and Bill V's, as well) is worthy of much more study!
